To all whom it may concern:

Be it known that I, HARRY J. SMITH, a subject of the Queen of GreatBritain and Ireland, residing in the city and county of Philadelphia, inthe State of Pennsylvania, have invented certain new and usefulImprovements in Condensers, of which the following is a true and exactdescription, reference being had to the accompanying drawings,which forma part thereof.

My invention relates to the construction of condensers for separatingcondensable matter from gas, and is particularly designed for use in thepurification of gas derived as a byproduct in coke-ovens, althoughadapted for use with gas from any other producer.

The object of my invention is to provide a condenser of great simplicityand efficiency of construction, and my invention will be best understoodas described in connection with the drawings, in which it isillustrated,

and in which Figure 1 is a side elevation of a condenser embodying myimprovements, the view being taken on the section-line a; x of Fig. 2.Fig. 2 is a plan view of the condenser with a top plate a removed toshow its interior construction, and Fig. 3 is a cross-sectionalelevation taken as on the line y 'y of Fig. 1 and shown on an enlargedscale.

A indicates a chamber which may be conveniently formed of iron platesand is provided with an entrance-port A and an exhaust-port A, by whichit is connected in a gas-conduit, and I may here explain that Icontemplate connecting several such condensers as are shown in thedrawings with the gas-conduit leading from the gas-producing ovens. Thelower edge of the openings A and A are preferably situated, as shown, atsome distance above the bottom of the chamber A, so as to form at thebottom of said chamber a reservoir for condensed liquids. Such areservoir may, however, be formed, if desired, in connection with, butnot as a part of, the chamber A.

a indicates the top plate or lid of the chamber A, which in theconstruction illustrated in the drawings is formed with transverseopenings or slots a a &c., one of which extends along over each row ofthe boxes to be hereinafter described.

B B, the. indicate parallel rows of wide and thin boxes, such as areindicated at B, &c., Fig. 3. They may conveniently be made of cast-ironand are formed with openings 1) b on opposite sidesone at the top andone at the bottomso that when the wide and thin boxes are erected andset side by side, as shown in Fig. 3, they form a continuous conduit forcold fluid. The joints adjacent to the openings 1) are of coursesuitably packed and each series or block of boxes B is held together bymeans of a clamping device,which may conveniently consist of rods, suchas are indicated at 0 0. Each series of boxes extends across the chamberA, substantially filling it, leaving room for the passage of gas betweenthe adjacent relatively wide sides of the boxes and in the small spacesbetween the series of boxes and the walls of the chamber-a constructionwhich insures an exten sive contact between the walls of the boxes andthe gas passing through the chamber. Preferably I use a number of boxseries, such as B, connecting them together and with a source from whicha cold fluid, preferably water, can be drawn by means ofpipes, such asare indicated at D D, &c. By keeping the boxes cold their surfaces ofcourse act as condensing-surfaces for the producer-gases passing overthem and condensing the less volatile portions. The said construction ofthe condensing conduits, made up of the boxes,while a feature of myinvention is not in its broader sense an essential feature, and anyconvenient condensingconduitforming a partition across the chamber Awith interstices between its co'nvolutions for the passage of gas may beused within the sense of my broader claims.

E is a conduit connecting through its extension G with a pump H, whichby means of a suction-pipe communicates with a reservoir for condensedliquor. The conduit E connects through branches c c with a series ofchambers F F, &c., which, as shown, are situated on top of the plate aand are formed with longitudinal slots f, which register with the slot aand are thus opened along the tops of each box series B. By this or anyequivalent device the liquor is constantly pumped from the reservoirandforced to flow over the surfaces of the condensing-conduit made up ofthe boxes B. The film of tarry liquor IOO with which the boxes are thusconstantly covered greatly promotes the condensation and separation ofthe condensable matter in the gas.

The operation of my apparatus has been fully described with' thedescription of its parts and construction, and need not, therefore, befurther specified.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A condenser for separating condensable matter from gas consisting ofa chamber A adapted to connect in a gas-conduit in combination with oneor more series of wide and thin boxes B set side by side and connectedin series as described to form a conduit for cold fluid said series ofconnected boxes form ing partitions across the chamber A withinterstices for the passage of gas between them and in contact withtheir adjacent Walls.

2. A condenser for separating condensable matter from gas consisting ofa chamber A adapted to connect in a gasconduit in combination with oneor more series of wide and thin boxes 13' set side by side and connectedin series as described by transverse rods 0 O to form a conduit for coldfluid s'aid series of connected boxes forming partitions across thechamber A with interstices for the passage of gas between them and incontact with their adjacent walls.

3. A condenser for separating condensable matter from gas consisting ofa chamber A adapted to connect in a gas-conduit in combination with oneor more series of Wide and thin boxes B set side by side and connectedin series as described to form a conduit for cold fluid, said series ofconnected boxes form= ing partitions across the chamber A withinterstices for the passage of gas between them and in contact withtheir adjacent walls, delivery-openings a extending over each series ofconnected boxes, a reservoir for condensed liquor and a pump connectedto draw said liquor from the reservoir and force it through thedelivery-openings over the boxes.
